Methods Content analysis, by 39 nurse judges, divided into the phases of conceptual definition of the phenomenon of interest, construction of the structure of the phenomenon of interest and analysis of the judges on the built structure.  Results From the 22 indicators, 21 were considered relevant Impaired gas exchange. The indicators that obtained absolute relevance were Cyanosis, Hypercapnia, Hypoxemia and Tachycardia. The indicator Headache upon waking did not show any statistically significant relevance for the diagnosis. All conceptual and operational definitions were clear and precise.  Conclusion The indicators listed for Impaired gas exchange were relevant to the phenomenon, except Headache upon waking because it does not correspond to a safe manifestation to identify the diagnosis, according to the analysis of the judges. Each conceptual and operational definition was adequate for its indicator.<\/jats:p>","DOI":"10.1590\/1983-1447.2021.20200099","type":"journal-article","created":{"date-parts":[[2021,3,29]],"date-time":"2021-03-29T07:34:42Z","timestamp":1617003282000},"source":"Crossref","is-referenced-by-count":7,"title":["Content analysis of clinical indicators for Impaired gas exchange"],"prefix":"10.1590","volume":"42","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0876-3996","authenticated-orcid":false,"given":"L\u00edvia Maia","family":"Pascoal","sequence":"first","affiliation":[{"name":"Universidade Federal do Maranh\u00e3o,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5867-8023","authenticated-orcid":false,"given":"Marcos Ven\u00edcios de Oliveira","family":"Lopes","sequence":"additional","affiliation":[{"name":"Universidade Federal do Cear\u00e1,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8033-8831","authenticated-orcid":false,"given":"Viviane Martins da","family":"Silva","sequence":"additional","affiliation":[{"name":"Universidade Federal do Cear\u00e1,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4344-7737","authenticated-orcid":false,"given":"Camila Maciel","family":"Diniz","sequence":"additional","affiliation":[{"name":"Universidade Federal do Cear\u00e1,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7589-6962","authenticated-orcid":false,"given":"Mar\u00edlia Mendes","family":"Nunes","sequence":"additional","affiliation":[{"name":"Universidade Federal do Cear\u00e1,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3571-0267","authenticated-orcid":false,"given":"Vanessa Emille Carvalho de Sousa","family":"Freire","sequence":"additional","affiliation":[{"name":"Universidade Federal do Cear\u00e1,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6674-0755","authenticated-orcid":false,"given":"Beatriz Beltr\u00e3o","family":"Amorim","sequence":"additional","affiliation":[{"name":"Hospital Universit\u00e1rio Walter Cant\u00eddio,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"530","published-online":{"date-parts":[[2021]]},"reference":[{"issue":"13","key":"ref1","doi-asserted-by":"crossref","first-page":"1239","DOI":"10.1001\/jama.2020.2648","article-title":"Characteristics of and important lessons from the coronavirus disease 2019 (COVID-19) outbreak in China: summary of a report of 72 314 case from the Chinese Center for Disease Control and Prevention","volume":"323","author":"Wu Z","year":"2020","journal-title":"JAMA"},{"key":"ref2","doi-asserted-by":"crossref","DOI":"10.1186\/s12985-016-0479-5","article-title":"Coronaviruses and the human airway: a universal system for virus-host interaction studies","volume":"13","author":"Jonsdottir HR","year":"2016","journal-title":"Virol J"},{"key":"ref3","series-title":"Coronavirus disease 2019 (COVID-19): Situation Report -
